I have a string of 6 solar panels (14A, 40V, 585W each) that I'm hoping to use to run my essential loads directly without any batteries or connection to the grid. I'm on the lookout for a budget-friendly inverter or any device that can take the DC input from my panels and convert it to 220V AC. It would be great if the inverter could have an option for battery input, but it's not a dealbreaker if it doesn't.

Honestly, it's pretty tough to run equipment without batteries. Solar output can fluctuate with cloud cover, and you need a constant power supply for AC loads. Without batteries, your system might shut down if the solar power dips too low. I strongly recommend looking into a battery solution for reliability, especially for nighttime use.
Running loads directly off solar panels is tricky because the voltage isn't stable enough for most appliances. If you're powering something like a water heater, it might work, but you really should consider a small battery setup or an MPPT charge controller to manage the power better.
You might need to include some form of battery. There are resources like "DIY Solar" on YouTube that could help you figure things out. It's a great place to start if you're looking for practical advice and setups.
Thanks for the advice! I understand the need for stability now. Any specific types of batteries you'd recommend?
